If you create a standard switch without physical network adapters, all traffic on that switch is confined to that switch. No other hosts on the physical network or virtual machines on other standard switches can send or receive traffic over this standard switch. You might create a standard switch without physical network adapters if you want a group of virtual machines to be able to communicate with each other, but not with other hosts or with virtual machines outside the group.

Click Add adapters.

Select an adapter from the Network Adapters list.

Use the Failover order group drop-down menu to assign the adapter to Active adapters, Standby adapters, or Unused adapters, and click OK.

(Optional) Use the up and down arrows in the Assigned adapters list to change the position of the adapter if needed.

Click Next.

On the Connection settings page, identify traffic through the ports of the group.

Type a Network label for the port group, or accept the generated label.
